Unfortunately there is no vaccine for preventing the Hepatitis C virus (HCV) which can lead to damage of the liver and other serious complications.
The good news is that there is treatment for Hepatitis C infection. In recent years newer treatments have paved way for better management and in most cases, hepatitis C is curable.
Even though there is treatment available, a large number of people with HCV do not know that they have been infected until liver damage occurs that is because symptoms can take years or decades to appear. Thus it is important to get tested if a person thinks that they had an exposure to the virus.
Getting tested and seeking treatment early is an effective way to manage Hep C. You may find this post on Hep C useful.
